I bought the Niplette for cosmetic reasons as I have always been self concious of having flat nipples. I have been using it for a week now for about 6 hours a day and the change is incredible. At first it feels a little odd, as if you know something is there but that lasts maybe half an hour, now I can wear them and not feel them at all. I been using a moisturiser as this both helps the nipplette to attach and also moisturises my nipples at the same time. They both now stay erect and have a wonderful shape, I also have the added bonus that they are quite sensitive now, something they never have been before. This has made me feel sexy and I now no longer have a hang up about having flat nipples, wonderful product.
